After the reset type gear shifting knob rotates in different rotation directions and different rotation angle ranges, different rotation strokes can be correspondingly formed, and different target gears can be correspondingly selected. After the knob rotating direction and the knob rotating range generated after the reset type gear shifting knob in the gear shifting operation parameters is rotated are obtained, what the required gear corresponding to the user operation is determined only by combining and judging the switching operation parameters triggered by the user and the current first gear, the logic judgment process is simplified, the accuracy of the user requested gear determined based on the user operation is ensured, the user requested gear is determined by combining the current gear on the basis of the user operation, and misoperation and invalid operation are avoided.

According to the electronic gear shifting processing method, gear shifting operation parameters generated after an electronic gear shifting device is operated are obtained, a first gear where a vehicle is located at present is obtained, a user request gear is determined according to the first gear and a knob rotating direction and a knob rotating range generated after a reset type gear shifting knob in the gear shifting operation parameters is rotated, the simple and convenient operation of a user is realized, the user experience is improved, meanwhile, the logic judgment in the gear shifting processing process is ensured to be simple and reliable, the user request gear determined based on the user operation is ensured to have accuracy, the misoperation and the invalid operation can be avoided, and the usability and the safety of automobile driving are improved.

Specifically, the following describes a process of determining a gear requested by a user, with reference to an actual gear condition of a currently located first gear.

In a first aspect, when the first gear is a neutral gear, as a preferred embodiment, the step of determining a user-requested gear according to the first gear and the gear-shifting operation parameter includes:

when the first gear is a neutral gear, if the rotation direction of the knob is the first direction and the rotation range of the knob is a stroke, determining that the gear requested by a user is the neutral gear; if the rotation direction of the knob is the first direction and the rotation range of the knob is two strokes, determining that the gear requested by the user is a second gear; if the rotation direction of the knob is a second direction and the rotation range of the knob is a stroke, determining that the gear requested by the user is a neutral gear; and if the rotation direction of the knob is the second direction and the rotation range of the knob is two strokes, determining that the gear requested by the user is the third gear.

Specifically, the first direction may preferably be a left direction, and the second direction is preferably a right direction; the second gear and the third gear are not neutral gears, the second gear and the third gear are different gears, specifically, the second gear and the third gear can be gears corresponding to different automobile traveling directions, the second gear can be preferably a reverse gear, the third gear is preferably a forward gear, and the gears can be specifically set according to actual needs and are not specifically limited herein.

Here, it is preferable that the user rotates the reset type shift knob to the left side to shift to the reverse gear and rotates the reset type shift knob to the right side to shift to the forward gear in order to conform to a normal knob operation and to ensure conformity to a user operation habit.

When the whole vehicle is initially electrified, the gear request is defaulted to neutral. When the current gear is in a neutral gear, the gear requested by a user is determined to be a reverse gear instead of a first stroke when the knob is rotated to a second stroke on the left side, so that the gear shifting operation is prevented from being performed by misoperation of the user, and the gear shifting intention of the user can be clarified by rotating the knob to the second stroke.

Similarly, the fact that the user requests the gear to be the forward gear instead of the first stroke is determined when the knob is rotated to the second stroke on the right side is used for preventing the user from operating the gear shifting operation by mistake, and the fact that the knob is rotated to the second stroke allows the gear shifting to be more clear of the gear shifting intention of the user.

The process sets different rotating directions of the knob and different knob rotating ranges in each direction, when a user rotates the knob, the operation intention of the user is determined through rotating parameters corresponding to operation, the current gear is combined, and false triggering or invalid gear shifting operation of the gear shifting operation is avoided through combination with the current actual gear. Through the acquisition of the knob rotation direction and the knob rotation range generated after the user rotates the reset type gear shifting knob and the combination of the current gear, the user request gear is determined, the safe and simple operation of the gear shifting process is realized, the logic judgment in the electronic gear shifting process is simple and reliable, the accuracy of the user request gear determined and obtained based on the user operation is ensured, and the usability and the safety of automobile driving are improved.

In the second aspect, as a preferred embodiment, when the first gear is a forward gear, the step of determining a user requested gear according to the first gear and the gear shift operation parameter includes:

when the first gear is a forward gear, if the rotation direction of the knob is different from the set switching rotation direction corresponding to the forward gear, and the rotation range of the knob is two strokes, determining that the gear requested by the user is a fourth gear; if the rotating direction of the knob is different from the set switching rotating direction corresponding to the forward gear and the rotating range of the knob is one stroke, determining that the gear requested by the user is a neutral gear; and if the rotation direction of the knob is the same as the set switching rotation direction corresponding to the forward gear, determining that the gear requested by the user is the forward gear.

The fourth gear is not a forward gear, the fourth gear is preferably a gear corresponding to a different vehicle driving direction from the forward gear, and the fourth gear may be a reverse gear corresponding to an opposite vehicle driving direction from the forward gear.

The set switching rotation direction corresponding to the forward gear can be a left direction or a right direction, preferably a right direction, and when the current gear is the forward gear and the operation parameters of the reset type gear shifting knob which is rotated towards the right direction for two strokes are acquired, the gear requested by the user is determined to be a reverse gear; if the reset type gear shifting knob is obtained to rotate towards the left direction, whether the rotation range is one stroke or two strokes is considered to be the same as the set switching rotation direction of the forward gear, the gear requested by a user is determined to be the forward gear, switching triggering between the forward gear and other gears is achieved through the reset type gear shifting knob, misoperation can be effectively eliminated, and effectiveness of gear switching judgment is guaranteed.

In a third aspect, when the first gear is a reverse gear, as a preferred embodiment, the step of determining a gear requested by a user according to the first gear and the gear shift operation parameter includes:

when the first gear is a reverse gear, if the rotation direction of the knob is different from the set switching rotation direction corresponding to the reverse gear, and the rotation range of the knob is two strokes, determining that the gear requested by the user is a fifth gear; if the rotating direction of the knob is different from the set switching rotating direction corresponding to the reverse gear, and the rotating range of the knob is a stroke, determining that the gear requested by the user is a neutral gear; and if the rotation direction of the knob is the same as the set switching rotation direction corresponding to the reverse gear, determining that the gear requested by the user is the reverse gear.

The fifth gear is not a reverse gear, the fifth gear is preferably a gear corresponding to a different vehicle traveling direction from the reverse gear, and the fifth gear may be a forward gear corresponding to a vehicle traveling direction opposite to the reverse gear.

The set switching rotation direction corresponding to the reverse gear can be a left direction or a right direction, preferably the left direction, and when the current gear is the reverse gear and the operation parameters of the reset type gear shifting knob which is rotated towards the left direction for two strokes are acquired, the gear requested by a user is determined to be a forward gear; if the reset type gear shifting knob is obtained to rotate towards the left direction, whether the rotation range is one stroke or two strokes is considered to be the same as the set switching rotation direction of the reverse gear, the gear requested by a user is determined to be the reverse gear, switching triggering between the reverse gear and other gears is achieved through the reset type gear shifting knob, misoperation can be effectively eliminated, and effectiveness of gear switching judgment is guaranteed.

As a preferred embodiment, the shift range operation parameters further include: the push type gear shifting button is used for shifting at least two preset driving gears according to a button pressing parameter generated after the button pressing operation is carried out.

Correspondingly, the step of determining the gear requested by the user according to the first gear and the gear switching operation parameter includes:

judging whether the first gear is one of the preset at least two driving gears or not, and judging whether the reset type gear shifting knob is reset to an original position or not; and if the judgment result is yes, determining that the target gear corresponding to the first button pressing operation in the preset at least two driving gears is the user request gear according to the first button pressing operation corresponding to the button pressing parameter.

The target gear corresponding to the first button pressing operation is one of at least two preset driving gears, the target gear is different from the first gear, the push type gear switching button generates a button pressing parameter after being subjected to the button pressing operation, whether the button is pressed or not can be judged according to the button pressing parameter, and if the button is pressed, the corresponding gear switching requirement is obtained.

The process of determining, according to the first button pressing operation corresponding to the button pressing parameter, that a target gear corresponding to the first button pressing operation in the at least two preset driving gears is the user requested gear may be that, according to the first button pressing operation, according to a preset gear switching sequence, a target gear corresponding to the first button pressing operation is determined from at least two preset driving gears, and the target gear is a set gear arranged after the first gear in the preset gear switching sequence.

The push button pressing operation of the push type gear shifting button is used for shifting at least two preset running gears, preferably, the at least two preset running gears can be a forward gear and a moving gear corresponding to the running direction of the advancing vehicle.

Specifically, with reference to tables one and two, when the shift operation parameters include: the process of determining the gear requested by the user according to the first gear and the gear switching operation parameter of the vehicle at present when the knob rotation direction and the knob rotation range generated after the reset type gear shifting knob is rotated and the button pressing parameter generated after the push type gear switching button is subjected to the button pressing operation is as follows.

With reference to the table i, the second gear is a reverse gear, the third gear is a forward gear, the first direction is a left direction, and the second direction is a right direction.

When the current gear is a reverse gear, when the fact that a user rotates a gear shifting knob to a second stroke leftwards is detected, whether a push type gear shifting button is pressed down is displayed by a button pressing parameter, a user request gear is determined to be the reverse gear, when the fact that the user rotates the gear shifting knob to the second stroke rightwards is detected, whether the push type gear shifting button is pressed down is displayed by the button pressing parameter, a user request gear is determined to be a forward gear, when the current gear is a neutral gear, when the fact that the user rotates the gear shifting knob to the first stroke leftwards is detected, whether the push type gear shifting button is pressed down is displayed by the button pressing parameter, the gear request is kept to be the neutral gear; when the current gear is neutral, when detecting that the user will shift the knob and rotate right to first stroke, no matter whether the button presses the parameter display push type gear switching button and presses, the gear request keeps neutral.

Specifically, the fourth gear is taken as a reverse gear, and the set switching rotational direction corresponding to the forward gear is taken as a right direction.

When the current gear is a forward gear, whether a button pressing parameter shows that a pressing type gear switching button is pressed down or not is judged whether the gear shifting knob is detected to be rotated leftwards to a first stroke by a user, and the gear requested by the user is determined to be a neutral gear; when the current gear is a forward gear, and when the fact that a user rotates the gear shifting knob to a second stroke leftwards is detected, whether a button pressing parameter shows that a pressing type gear shifting button is pressed down or not is judged, the fact that the gear requested by the user is a reverse gear is determined; when the current gear is a forward gear, when the user is detected to rotate the gear shifting knob to the right to a first stroke or a second stroke, no matter whether the button pressing parameter display pressing type gear switching button is pressed or not, the gear request is to keep the forward gear.

Similarly, when the current gear is one of the forward gears or a gear branch, such as a sport gear or an economy gear, the gear shift process is considered to be the same as the forward gear, for example, when the current gear is the sport gear, when it is detected that the user rotates the gear shift knob to the left to reach a first stroke, whether the button pressing parameter display pressing type gear shift button is pressed or not is determined that the user requests the gear to be a neutral gear; when the current gear is a moving gear, whether a button pressing parameter shows that a pressing type gear switching button is pressed down or not is judged whether the gear shifting knob is rotated leftwards to a second stroke by a user is detected, and the gear requested by the user is a reverse gear; when the current gear is a motion gear, when detecting that a user turns the gear shifting knob to the right to a first stroke or a second stroke, no matter whether the button pressing parameter display pressing type gear switching button is pressed or not, the gear request is for keeping the motion gear.

Specifically, the fifth gear is taken as a forward gear, and the set switching rotational direction corresponding to the reverse gear is taken as a left direction.

When the current gear is a reverse gear, whether a button pressing parameter shows that a pressing type gear switching button is pressed down or not is judged whether a user rotates a gear shifting knob to a first stroke rightwards or not is detected, and the gear requested by the user is determined to be a neutral gear; when the current gear is the reverse gear, whether a button pressing parameter shows that a pressing type gear switching button is pressed down or not is judged when the gear shifting knob is detected to be rotated rightwards by a user to a second stroke by the user, and the gear requested by the user is determined to be the reverse gear; when the current gear is in reverse gear, when detecting that the user will shift the knob and turn left to first stroke or second stroke, no matter whether the button is pressed down the parameter display push type gear switching button and pressed down, the gear request is for keeping reverse gear.

Watch 1

The signals of vehicle running signals, vehicle speed, braking signals, motor rotation direction and the like formed by the operation of the drivers are integrated to judge whether to respond to the gear shifting operation requirement of the user, the gear shifting operation is implemented, the gear requested by the user is further judged, the validity of the gear shifting request of the user is ensured, and misoperation and invalid operation are avoided.

As a preferred embodiment, wherein the step of determining whether the user requested gear corresponds to a valid shift request based on the user requested gear and/or vehicle operating parameters comprises:

if the user requested gear is a neutral gear, determining that the user requested gear corresponds to an effective gear shifting request; if the user requested gear is not a neutral gear and the current vehicle speed in the vehicle operation parameters is within a set vehicle speed range which is larger than 0 and smaller than a set value, determining that the user requested gear corresponds to an effective gear shifting request; if the user requested gear is not a neutral gear, and the current vehicle speed in the vehicle operation parameters is 0 and the brake pedal is pressed down, determining that the user requested gear corresponds to an effective gear shifting request; if the user requested gear is not a neutral gear, the current speed in the vehicle operation parameters is greater than the set value, and the motor rotation direction is consistent with the motor rotation direction required by the user requested gear, determining that the user requested gear corresponds to an effective gear shifting request; otherwise, determining that the user requested gear corresponds to an invalid shift request and maintaining the first gear.

The push button pressing operation of the push type gear shifting button is used for shifting at least two preset running gears, and if the user request gear is one of the at least two preset running gears and the user request gear is the other one of the at least two preset running gears, it is determined that the user request gear corresponds to an effective gear shifting request. When the vehicle operating parameters indicate that the gear shifting device of the vehicle is malfunctioning, the user-requested gear is deemed to correspond to an invalid shift request.

When the whole vehicle is initially electrified, the control gear in the vehicle is defaulted to be neutral.

Combining with a third table, if the current gear is a neutral gear, and if the user requests the gear to be a reverse gear, and when the vehicle speed is 0 and the conditions such as the user steps on a brake pedal are met simultaneously, the actual gear is switched to the reverse gear; the vehicle speed is 0, the vehicle is considered to be static, and the user only allows the reverse gear to be switched when the user steps on the brake pedal, so that sudden rush-out of the vehicle when the vehicle is started is avoided when the vehicle is switched from static to driving gear.

When the vehicle speed is greater than 0 and lower than a certain vehicle speed threshold value, gear shifting can be performed without stepping on braking, and therefore a user can conveniently and frequently switch forward and backward gears at a low speed. When the vehicle speed is higher than a certain vehicle speed threshold value, if the rotating direction of the motor is reverse and is consistent with the direction of the gear operation intention of a user, switching to reverse gear is allowed; if the rotation direction of the motor is positive rotation, the motor is not allowed to be switched to the reverse gear, the switching of the forward gear and the reverse gear at high speed is avoided, and the misoperation of a user is considered.

When the current gear is a neutral gear, if the user requests the gear to be a forward gear, when the vehicle speed is 0 and the conditions that the user steps on a brake pedal and the like are simultaneously met, the actual gear is switched to the forward gear; the vehicle is considered to be static when the vehicle speed is 0, and the user only allows the vehicle to be switched to the forward gear when the user steps on the brake pedal, so that sudden rush-out of the vehicle when the vehicle is switched from static to driving gear is avoided. When the vehicle speed is greater than 0 and lower than a certain vehicle speed threshold value, gear shifting can be performed without stepping on braking, and the user can conveniently and frequently switch forward and backward gear positions at low speed. When the vehicle speed is higher than a certain vehicle speed threshold value, if the rotating direction of the motor is positive rotation and is consistent with the direction of the intention of the user to operate the gear, the motor is allowed to be switched to a forward gear; if the rotation direction of the motor is reverse, the motor is not allowed to be switched to the forward gear, the user is considered to operate by mistake, and the forward gear and the backward gear are prevented from being switched at high speed.

When the current gear is a reverse gear, if a user requests that the gear is a neutral gear, the gear is directly switched to the neutral gear no matter what the vehicle speed, the braking signal and the rotating direction of the motor are; when the current gear is a forward gear, if the gear request is a neutral gear, the gear is directly switched to the neutral gear no matter what the vehicle speed, the braking signal and the rotating direction of the motor are; when the current gear is a motion gear, if a user requests that the gear is a neutral gear, the gear is directly switched to the neutral gear no matter what the vehicle speed, the braking signal and the rotating direction of the motor are; the user can be guaranteed to switch to the neutral gear at any time.

When the current gear is a forward gear, if a user requests that the gear is a reverse gear, if the vehicle speed is 0 and a brake pedal is stepped on, switching to the reverse gear is allowed; when the vehicle speed is greater than 0 and lower than a certain vehicle speed threshold value, gear shifting can be performed without stepping on braking, and the user can conveniently and frequently switch forward and backward gear positions at low speed.

When the current gear is a reverse gear, if a user requests that the gear is a forward gear, if the vehicle speed is 0 and a brake pedal is stepped on, switching to the forward gear is allowed; when the vehicle speed is greater than 0 and lower than a certain vehicle speed threshold value, gear shifting can be performed without stepping on braking, and the user can conveniently and frequently switch forward and backward gear positions at low speed.

When the current gear is a forward gear, if a user requests that the gear is a motion gear, directly switching to the motion gear; when the current gear is a motion gear, if a user requests that the gear is a forward gear, directly switching to the forward gear; the forward gear and the motion gear can be switched freely under any condition by a user.

Watch III

The shift operation in the table above is an effective shift request, and when the shifter is not faulty and the shift operation does not satisfy the above conditions, the operation strategy gear keeps the original gear. Under the driving mode, after the high-voltage electrification is finished, the automobile carries out gear shifting misoperation judgment, and gear shifting misoperation is judged if the gear shifting operation is not in accordance with the constraint of table three.

Specifically, in the foregoing embodiment, a part of the contents of the embodiment of the process for determining the gear requested by the user and a part of the contents of the embodiment of the process for performing the gear switching determination according to the determined gear requested by the user may be performed corresponding to the same execution device, for example, an electronic gear shifting processor in the whole automobile, the process for determining the gear requested by the user and the process for performing the gear determination and switching according to the determined gear requested by the user are implemented.

Or, the contents of the two embodiments are executed by matching different executing devices in the automobile, and in combination with the description of fig. 4, the contents of a part of the embodiment of the process for determining the gear requested by the user are executed by a reset type electronic gear shifting control unit in the whole automobile; and according to the determined gear requested by the user, the processes of gear judgment and gear switching are executed by the vehicle control unit. The reset type electronic gear shifting control unit is responsible for acquiring operation signals of a reset type gear shifting knob and a push type gear shifting button, identifying a gear shifting request, determining a user requested gear, sending the gear shifting request to the whole vehicle Controller through a Controller Area Network (CAN) message, and the whole vehicle Controller is responsible for strategic gear shifting control, determining the effectiveness of the requested gear, and implementing gear shifting control according to the determined control gear.

The instrument shows four fender positions of reverse gear, neutral gear, forward gear and motion gear in the car, and the fender position device panel is provided with four fender position indicator lamps of reverse gear, neutral gear, forward gear and motion gear. The vehicle control unit sends the determined control gear signal to the reset type electronic gear shifting control unit and the instrument display unit, and the instrument display unit lights corresponding gear indicator lamps according to the received strategy gears corresponding to the actual gear signal.

As a preferred embodiment, after the step of determining that the user requested gear corresponds to an invalid shift request and maintaining the first gear, the electronic shift processing method further includes:

When the situation that the gear requested by the user corresponds to the invalid gear shifting request is determined, the current gear is kept unchanged, warning information is sent aiming at the invalid gear shifting request, specifically, a warning sound is sent to serve as a prompt, the invalid gear shifting request can be regarded as that the driver has gear shifting misoperation, at the moment, the vehicle controller can send the gear shifting misoperation mark bit to the instrument display unit through the bus, and the instrument display unit carries out short-ringing warning sound to prompt the driver. When the vehicle controller detects a gear request sent by the reset type electronic gear shifting control unit, and after the detected gear request is switched to be consistent with the current actual gear, gear shifting misoperation is eliminated, and warning information is eliminated.

As a preferred embodiment, after the step of determining the gear requested by the user according to the first gear and the gear shift operation parameter, the method further includes:

if the electronic gear shifting device is detected to be in fault or a communication line is detected to be in signal loss fault, judging whether the current vehicle speed is greater than a set vehicle speed threshold value or not; if the judgment result is yes, keeping the first gear;

When the vehicle control unit judges that the gear is in fault, a fault state is sent out through the CAN, and the gear fault is displayed through the instrument to remind a driver. The electronic gear shifting device is characterized in that a reset type gear shifting knob or a push type gear shifting button is failed, and a signal loss fault of a communication circuit is specifically a fault that a whole vehicle controller determines that a reset type electronic gear shifting control unit is in communication loss. If the current vehicle speed is greater than or equal to a certain vehicle speed threshold value, the actual gear is kept unchanged, the vehicle controller does not respond to a new gear shifting input request of the reset type electronic gear shifting control unit, and unexpected gear shifting of the vehicle caused by gear faults under the condition of unconsciousness of a driver is avoided when the vehicle runs at a high speed. And if the current vehicle speed is less than a certain vehicle speed threshold value, the actual gear is neutral, and the vehicle controller does not respond to a new gear shifting input request of the reset electronic gear shifting control unit.

When the fact that only the press type gear shifting button fails is detected, the vehicle control unit does not respond to switching operation between at least two preset driving gears corresponding to the press type gear shifting button for switching, specifically, the vehicle control unit does not respond to switching between an advancing gear and a moving gear, and other gears corresponding to the reset type gear shifting knob are normally shifted to respond normally, so that normal gear shifting of a user is guaranteed, and driving gear shifting requirements are met.

As a preferred embodiment, after the step of determining the gear requested by the user according to the first gear and the gear shift operation parameter, the electronic gear shift processing method further includes:

And assuming that the vehicle control unit does not respond to the gear shift request of the user, the user requests that the gear shift is switched to the original gear. When gear shifting operation is carried out, gear requests are changed, timing is started after a new gear request is sent out by a reset type electronic gear shifting control unit, and if the actual gear is switched to be consistent with the gear requested by a user within the effective time threshold of the gear request, the gear request is kept; and if the effective gear determined by the vehicle control unit is not consistent with the user requested gear after the gear request effective time threshold, the user requests the gear to be switched to the original requested gear so as to perform gear processing when the signal fails.

Above-mentioned process has given the solution that resets formula electron and shift gears and instrument demonstration to retrain the fender position maloperation that the user probably appears and keep off the position trouble, indicate the user through the instrument and keep off the position maloperation and keep off the position trouble, solved the problem that the actual fender position control was reminded with keeping off the position maloperation, improved user experience.
